Description

气动偏心调节阀
技术领域
本发明涉及阀门技术领域。具体来说涉及一种气动偏心调节阀。
背景技术
目前市场上通用的气动偏心调节阀都采用中心式结构，这种结构的阀体其流通性能差，阀结合部易产生积垢、阻塞、造成阀芯阀座严重磨损。因此，如何解决上述问题是本领域技术人员需要研究的方向。
发明内容
为解决上述问题，本发明提供了一种气动偏心调节阀。
其采用的方案如下：
一种气动偏心调节阀，包括：气缸、阀杆、密封件、阀芯和阀体；所述阀体上设有导入孔和流体管；所述阀杆一端安装于气缸的输出端，由气缸驱动沿轴向旋转；另一端经导入孔伸入阀体内；所述阀芯位于流体管内、安装于阀杆轴向，在气缸驱动下随阀杆同步转动，令阀体打开/关堵流体管；所述密封件位于阀杆与导入孔的连接处。
通过采用这种技术方案：阀芯采用偏心设计，在气缸驱动下随阀杆轴向运动实现流体管的打开/关堵，相对于传统的中心式结构阀芯其流通性能更好，且不易产生积垢，减少了磨损，提高了使用寿命。
优选的是，上述气动偏心调节阀中：所述密封件包括密封填料，密封填料压盖和压板；所述压板位于密封填料压盖上端、将密封填料压盖压于密封填料上，所述密封填料设于阀杆与上阀盖的连接处。更优选的是，所述密封填料为四氟乙烯-全氟烷氧基乙烯基醚共聚物。
通过采用这种技术方案：利用作为密封填料的四氟乙烯-全氟烷氧基乙烯基醚共聚物本身不易磨损的特性，进一步提升了密封填料的使用寿命。
进一步优选的是，上述气动偏心调节阀中：还包括压圈螺母，所述压圈螺母安装于流体管内壁。
与现有技术相比，本发明结构简单，易于实现。具有更好的流通性能，不易产生积垢，大大减少了阀芯和阀座的磨损，提高了阀体的使用寿命。
